Fast-Drying Swimsuits

Just like our workout gear, Under Armour boys’ swimwear and swim sets are built for athletes. What’s that mean? Comfort and performance, and lots of it. Find a new pair of boys’ swim shorts that are stretchy so you can move in all directions, lightweight so you’re not getting dragged down by any water weight, and quick-drying to avoid that uncomfortable, water-to-sand feeling you can get on the beach with a wet bathing suit. You know the one.

Protect yourself when you’re out in a bathing suit, too. Find boys’ swimsuits with UPF 50+ that’ll help protect your skin from the sun’s harmful rays. Check out short and long sleeve surf shirts made with the same protection, as well as stretchy fabrics that come with a fitted or loose fit.

Show a bit of personality with a matching swim set. Not only are the designs unique in their patterns and colors, the swimsuits and surf shirts that come with them feature fabrics and materials that are made to keep you comfortable, while some shorts options have salt and chlorine-resistant materials that help prevent fading. That way, you’re able to preserve the life of your swimwear through the Summer and beyond. Our boys’ swimsuits are all lightweight, durable, quick-drying—everything you need.
